Many of the rules for the euphony of consonants were not established in the classical period. Inscriptions show a much freer practice, either marking the etymology, as σύνμαχος for σύμμαχοςally ( cross94), ἐνκαλεῖν for ἐγκαλεῖνto bring a charge ( cross92), or showing the actual pronunciation (phonetic spelling), as τὸγ (= τὸν) κακόν ( cross92), τὴμ (= τὴν) βουλήν ( cross91), τὸλ (= τὸν) λόγον, ἔγδοσις for ἔκδοσιςsurrendering ( cross104), ἐχφέρω, ἐχθύ_ω for ἐκφέρω, ἐκθύ_ω ( cross104).
